Although Solid State Drives (SSD) have been available for some time, they are still quite pricey when you want a higher capacity. Laptops manufacturers use them for primary storage in configs of 128GB or 256GB but anything higher than that becomes expensive. Until prices for 1TB or higher SSD drives become more affordable, we continue using traditional hard drives for mainstream storage and in order to accommodate that, we’re using more external drives. I ‘m looking a one such drive today- the Lacie d2 Thunderbolt.

 Lacie is the more upscale/higher-end brand belonging to Seagate which is one of the largest storage manufacturers in the world. Packaged nicely is a mid-sized box, the Lacie d2 Thunderbolt comes equipped with a power adapter, a USB Type-C to Type-C cable and a USB Type A to Type-C cable. While this covers pretty much any recent computer, I would have liked to see a cable that was Type-C to Mini-DP which would allow me to use this Lacie d2 with a Thunderbolt connection on the older MacBook Pro.

 The Lacie d2 is a hefty dense block of metal as far as design is concerned. With sharp edges and an aluminum chassis, the design is very classy. A blue button sits on the front while the back has connections for power, USB 3.1 and Thunderbolt. The Lacie d2 supports daisy chaining using Thunderbolt so you don't lose any ports connecting it to your computer. It supports both Mac and Windows and the model I received for review had a 6TB 7200RPM hard drive.

I connected it to my office MacBook Pro which is a couple of years old and used USB 3.1 for this. Following that, I ran the LaCie Setup Assistant that allowed me to format the drive as FAT32 or HFS+ or a combination of the two. I selected the latter splitting the drive into a 2TB FAT32 volume and a 4TB HFS+ volume which allowed me to share the drive with my colleagues using Windows while at the same time using HFS+ on my Mac for getting the best performance and doing Time Machine Backups.

Once that was done, I had the two volumes show up on my desktop and I started my Time Machine Backup on the HFS+ which took about 40 minutes for the initial backup of roughly 14GB. I also ran Blackmagic disk speed test which showed both and read and write speeds a bit north of 200MB/s matching the advertised speeds on the box. While these aren’t necessarily super fast speeds, they’re good enough to store and access your data. 

What is more important is the reliability of your data and the fact that the Lacie d3 Thunderbolt 3 comes with a Seagate Barracuda Pro enterprise-class drive with a 5 year warranty gives me good peace of mind. Pricing for the 6TB version of the Lacie d2 Thunderbolt3 is right around AED 1999 which is a fair price for the capacity, reliability and the design you’re getting.

With Thunderbolt 3 and USB 3.1 speeds through the USB-C port, the new LaCie d2 performs perfectly on late model laptops such as the new MacBook Pro—as well as on USB 3.0-compatible computers.
